−(a−1)(b−1)(c−1)Which of the following is equivalent to the given expression?Choose 1 answer:(A) (1−a)(b−1)(1−c)(B) (1−a)(1−b)(1−c)(C) (a−1)(1−b)(1−c)(D) (1−a)(1−b)(c−1)
Q. −(a−1)(b−1)(c−1)Which of the following is equivalent to the given expression?Choose 1 answer:(A) (1−a)(b−1)(1−c)(B) (1−a)(1−b)(1−c)(C) (a−1)(1−b)(1−c)(D) (1−a)(1−b)(c−1)
Given Expression: We are given the expression −(a−1)(b−1)(c−1) and we need to find an equivalent expression among the options provided.
Distribute Negative Sign: Let's distribute the negative sign across the expression. This will change the sign of each term inside the parentheses.−(a−1)(b−1)(c−1)=(−1)⋅(a−1)(b−1)(c−1)
Apply Negative Sign: Now, we apply the negative sign to each term inside the first set of parentheses.(\(-1)\cdot(a−1)(b−1)(c−1) = (1-a)(b−1)(c−1)
Compare with Options: We can see that the expression \(1-a)(b−1)(c−1)\ is equivalent to the given expression. Now, let's compare this with the options provided.
Option (A): Option (A) is \(1-a)(b−1)(1-c)\, which is not equivalent to our expression because the sign of the last term c\(-1)\ is different.
Option (B): Option (B) is \(1-a)(1-b)(1-c)\, which is not equivalent to our expression because the signs of the second and third terms are different.
Option (C): Option (C) is a\(-1)(1-b)(1-c)\, which is not equivalent to our expression because the sign of the first term is different.
Option (D): Option (D) is \(1-a)(1-b)(c−1)\, which is not equivalent to our expression because the signs of the second and third terms are different.
Correct Equivalent Expression: The correct equivalent expression is not listed among the options provided. Therefore, none of the options (A), (B), (C), or (D) are equivalent to the given expression −(a−1)(b−1)(c−1).
